Free Amigurumi Patrick Star Keychain Pattern
If you love cute little crochet characters, this Patrick Star keychain is such a fun project to make. His simple pink body and little green shorts make him instantly recognizable, and because the finished piece is small, it doesn’t take a lot of yarn or time.
I made this pattern as a small keychain, but you can also use the finished Patrick as a backpack charm, bag accessory, or simply add him to your amigurumi collection.
The pattern uses basic amigurumi techniques such as single crochet, increases, decreases, stuffing, and sewing small pieces together. If you’re still getting comfortable with amigurumi, this is a nice project to practice those techniques on a small scale.
So, grab your pink and green yarn, and let’s crochet this little Patrick Star together! 🧶💕

Materials You’ll Need

You don’t need many supplies for this little Patrick Star keychain. Before you start, gather your yarn and a few basic crochet tools.
- Yarn: Pink, bright green, black, and white yarn. I used medium/worsted-weight yarn for this pattern.
- Crochet hook: 3.0–3.5 mm crochet hook. Choose a size that gives you firm stitches without making your work too difficult to crochet.
- Stuffing: Polyester fiberfill for filling the body and legs.
- Safety eyes: 6–8 mm safety eyes. You can also embroider the eyes with black yarn if you prefer.
- Keychain ring: A small metal keychain ring or split ring.
- Tapestry needle: For sewing the arms and legs and weaving in yarn ends.
- Scissors: For cutting the yarn.
- Stitch marker: Helpful for keeping track of your rounds when working in continuous spirals.
A Quick Note About Yarn and Hook Size
For amigurumi, it’s usually better to crochet with a slightly smaller hook than you would normally use for the same yarn. This helps keep the stitches close together so the stuffing doesn’t show through.
The exact hook size can vary depending on how tightly you crochet. If your stitches look loose, try going down a hook size. If your work feels extremely tight and difficult to crochet, try going up slightly.
You can also make a smaller Patrick by using thinner yarn and a smaller hook. Just keep in mind that the finished size will change.
Crochet Abbreviations
This pattern uses standard US crochet terms. Here are the abbreviations used throughout the pattern:
- MR: Magic Ring
- sc: Single Crochet
- inc: Increase — work 2 sc in the same stitch
- dec: Decrease — crochet 2 stitches together
- st / sts: Stitch / Stitches
- FO: Fasten Off
- ( ) x 6: Repeat the instructions inside the parentheses 6 times
The number at the end of each round shows the total number of stitches you should have after completing that round.
Tip: For a neater amigurumi finish, you can use an invisible decrease when the pattern calls for a decrease.
IV. Free Amigurumi Patrick Star Keychain Pattern
The body is crocheted in one piece, starting with pink yarn and changing to green for Patrick’s shorts. Work in continuous rounds rather than joining each round with a slip stitch.
Keep a stitch marker in the first stitch of each round so you can easily keep track of your place.
A. Body
Start with pink yarn.
| Round | Instructions | Total Stitches |
| R1 | 6 sc in a magic ring | 6 |
| R2 | inc in each stitch around | 12 |
| R3 | (sc, inc) × 6 | 18 |
| R4 | (2 sc, inc) × 6 | 24 |
| R5–R8 | sc in each stitch around | 24 |
| R9 | (2 sc, dec) × 6 | 18 |
| R10 | sc in each stitch around | 18 |
At this point, the pink section is complete and you can begin adding the facial details.
Eyes: Insert the safety eyes between R7 and R8, leaving approximately 5 stitches between them. If you prefer embroidered eyes, you can add them after the body is finished.
Stuffing: Start adding small amounts of polyester fiberfill as you work. Keep the stuffing firm enough to hold the shape, but avoid packing it so tightly that the stitches stretch and gaps appear.
B. Change to Green for the Shorts

For the next round, change from pink to green yarn.
| Round | Instructions | Total Stitches |
| R11 | (2 sc, inc) × 6 | 24 |
R12–R13 | sc in each stitch around | 24 |
| R14 | (2 sc, dec) × 6 | 18 |
| R15 | (sc, dec) × 6 | 12 |
| R16 | dec × 6 | 6 |
After R16, fasten off. Using a tapestry needle, weave the yarn tail through the front loops of the remaining 6 stitches and gently pull to close the opening. Secure and weave in the end.
Continue adding stuffing as you work through the green section, making sure the body remains evenly filled.
Tip: When changing from pink to green, make the color change at the end of R10. Complete the final stitch of R10 with the new green yarn for a cleaner transition.
C. Arms – Make 2
Use pink yarn.
The arms are small and simple to crochet. They can be left unstuffed, or you can add a tiny amount of fiberfill if you want them to have a little more shape.
| Round | Instructions | Total Stitches |
| R1 | 4 sc in a magic ring | 4 |
| R2 | (sc, inc) × 2 | 6 |
| R3–R4 | sc in each stitch around | 6 |
After R4, fasten off and leave a long yarn tail for sewing.
Do not overstuff the arms. If desired, add just a small amount of fiberfill before attaching them to the body.
D. Legs – Make 2
Use pink yarn.
The legs are slightly longer than the arms and are lightly stuffed to help them keep their shape.
| Round | Instructions | Total Stitches |
| R1 | 6 sc in a magic ring | 6 |
| R2 | (sc, inc) × 3 | 9 |
| R3–R4 | sc in each stitch around | 9 |
After R4, fasten off and leave a long yarn tail for sewing.
Add a small amount of fiberfill to each leg if desired. Avoid overstuffing, as the legs need to remain flexible enough to attach neatly to the body.
V. Assembly and Finishing
Now that all the crocheted pieces are ready, it’s time to put your little Patrick together.
Attaching the Arms and Legs

Use the long yarn tails left on the arms and legs to sew them securely to the body. Take your time with the placement so both sides look even.
Arms:
Sew the arms to the sides of the body, just below the pink section around R8. Make sure they are positioned evenly on both sides.
Legs:
Attach the legs to the lower part of the green shorts, around R13–R14. Place them evenly so Patrick can sit nicely and the keychain keeps its balance.
Once you’re happy with the placement, weave in the remaining yarn ends neatly.
Adding the Face
Mouth:
Use black yarn or embroidery thread to create Patrick’s smile. Embroider a wide curved smile below the eyes. You can make it simple or slightly wider for a more playful expression.
Eyebrows:
Add two small curved lines above the eyes using black yarn or embroidery thread. These little details help give Patrick his familiar, goofy expression.
Attaching the Keychain Ring
To turn your crochet Patrick into a keychain, attach a small metal keychain ring securely to the top of the body.
You can either attach the ring directly through the top stitches or make a small yarn loop and connect the ring to the loop.
Make sure the attachment is sewn firmly, especially if you plan to use the keychain regularly on your keys, backpack, or bag.
VI. Helpful Crochet Tips
A few simple techniques can make a big difference when working on a small amigurumi project like this one.
Invisible Decrease
An invisible decrease gives your amigurumi a smoother and neater finish.
To make one, insert your hook through the front loop only of the next stitch and then through the front loop of the following stitch. Yarn over, pull through both front loops, yarn over again, and pull through the remaining loops on your hook.
If you’re already comfortable with regular decreases, you can use those instead.
Changing Colors
When changing from pink to green, make the color change at the end of the last stitch of R10.
Work the stitch until you have two loops left on your hook. Drop the pink yarn, pick up the green yarn, and use the green yarn to complete the stitch.
This helps create a cleaner color transition between Patrick’s body and his shorts.
Keep Your Stitches Tight
Try to keep your tension firm and consistent while crocheting. Small gaps between stitches can allow the stuffing to show through.
If you naturally crochet loosely, try using a slightly smaller hook. The finished fabric should be firm, but not so tight that the stitches become difficult to work.
Use a Stitch Marker
Because the body is worked in continuous rounds, it can be easy to lose track of where a round begins.
Place a stitch marker in the first stitch of each round and move it up as you continue. This makes counting your stitches much easier and helps keep the shaping consistent.
A Few Tips for a Neat Finish
- Add stuffing gradually rather than filling the body all at once.
- Check the placement of the arms and legs before sewing them permanently.
- Hide yarn tails securely inside the body or between the stitches.
- Take a moment to check the overall shape before adding the final facial details.
VII. Frequently Asked Questions
Can a beginner crochet this Patrick Star keychain?
Yes! This pattern uses basic amigurumi stitches such as single crochet, increases, and decreases. If you’re comfortable with these stitches and know how to make a magic ring, you should be able to follow the pattern.
What yarn is best for a small amigurumi keychain?
Sport weight or light worsted weight yarn works well for a small keychain. The exact size will depend on your yarn, hook size, and crochet tension.
Cotton yarn is a great choice because it has good stitch definition and helps the finished piece keep its shape. You can also use acrylic yarn if that’s what you have on hand.
How do I change from pink to green?
Change to green yarn at the end of R10.
Work the last stitch of R10 until you have two loops left on your hook. Drop the pink yarn, pick up the green yarn, and use it to complete the stitch. Then continue with R11 in green.
How do I attach the keychain ring securely?
You can attach the ring directly to the top stitches of the body, or make a small yarn loop and attach the ring to it.
Whichever method you choose, make sure the connection is sewn securely. A strong attachment is especially important if the keychain will be used regularly on keys, a backpack, or a bag.
Can I make this pattern without sewing?
The main body is crocheted in one piece, but the arms and legs are made separately and need to be sewn onto the body.
If you prefer completely no-sew projects, you may want to look for a no-sew amigurumi pattern instead.
